The operation of our hand tool will bethreads lA the `body portion 1.- The up- -per extremity of the longitudinally extending rod 24 is provided .With a hand gri 28 which enables the rod 24 to be quick y ow-` understood from the preceding description.

It may be said'however by way of example lug or obstruction ory storage batter l tion of. the hand that the jaws 17 and 18 may be operated to their maximum distance by rotating the hand grip 7 of the rotatable' screw threaded member 3 to its next position on the spiral screw threads 2. The longitudinal rod 24 is elevated from a position adjacent the jaws by counter-clockwise rotation of the hand device 28. The tool is then lowered over the post represented at 29. Lug 30 is remove from the post 29 by quickly revolving the rotatable screw member 3 in aclockwise direc.i tion whereby the gripping jaws -22 and 23 .assume the position shown in Figure 2 of the drawings. Rod 24 is then lowered in position byrotating the hand'device 28 in a clockwise direction whereby the 'center 31 engages the top of ost 29. Continued rotaevice A,28 causes the faces 22 and 23 to be drawn upward and thereby operated to produce relative movement be tween'lug 30and the post 29 in pulling the corroded terminal from the storage batter The body portion 1 is substantially shaped, that is to say, -t-he end of the cylindrical body portion terminates in the laterally extending member 21 forming the top of the T in the extremities of which the gripping jaws 17 and 18 are pivoted. The T-shaped member is substantially smooth over one part of its cylindrical length on the exterior thereof but isscrew4 threaded over the upper extremity thereof as represesnted at 2 in the drawings. It will be ap reciated that our implement may be used or many different purposes and as we have hereinbefore stated we intend no limitations upon the invention other than that imposed by the scope of the appended claims.

What we claim Letters Patent of the United States is as follows:

1. A gripping and pullngtool comprising and desire to vsecure by Lacasse' a cylindrical body portion screw threaded on the upper extremity of the exterior sur face thereof, journals on opposite sides of the lower portion of said body portion, gripping jaws pivoted in said journals, a rota table screw threaded device operable upon said screw threaded portion, a laterally'extending member adapted to be reciprocated upon said body portion of said rotatable screw threaded device, links connecting the opposite sides of-said last mentioned member and -said grippingjaws whereby said v jaws may be quickly opened and closed, and screw threaded means extending `centrally through said body portion for laterally mov- 'ing said jaws with respect to a fixed point.

2. A hand gripping and'pulling tool comprising in combination a cylindrical body portion screw threaded on the exterior upper extremity thereof and having a laterally extending member on one end thereof, journals in each side of said member, pivoted grip ping jaws in said journals, a laterally extending member-ada ted to be reciprocated with respect to said rst mentioned laterally extending member,V links linterconnecting said jaws with said second mentioned laterally extending member whereby said jaws may be opened or closed for grip ing an object, and means extending throng said body i away from said T-shaped portion whereby said 'aws may be opened andclosed to grip an o ject, and a centrally disposed screw threaded member adapted to cause said jaws to move with respect to said object.
